It seems this library is currently incompatible with the ATmega32u4 from the Arduino Leonardo (built into a DFrobot Romeo in my case). Could this library be made compatible? This SBUS library would be great on this robot controller! Thank you.

Here is my Arduino IDE 1.6.4 error messages:

Servo Motor Shaking Problem.

Is there any way stop servo from shaking?

I am using this sbus in developing an esp32 based program and I'm not sure if it is capable for the esp32 kit.

Great library! It should be included to PlatformIO so we can install it using the automatic package manager it has. Would you accept a PR for a platformio.json file in the repo?

I don't understand why you can't invert the signal inside Arduino. It makes no sense to use hardware to do that.

Hey- thanks for this awesome library. I am having trouble getting it going on an arduino Mega, using a Futaba TX/RX setup. I have a 2N3904/10k/4.7k TTL inverter. The one thing that is curious is that the sbus.getDecoderErrorFrames() value keeps climbing when the Rx is connected and sbus.getDecoderErrorFrames() stops counting the instant I disconnect the Rx.

So it's definitely seeing the receiver, but for some reason all channels are showing as -100 and 100% of data is being lost.

Hi,
the SBUS converter i made according to SBUS_inverter.png doesn't work for me.
I use this one here:

When I run a verify I get the error:

Hi!
I have been using the FUTABA-SBUS library for a long time. Always used parameters 100000, SERIAL_8E2. You have 115200, SERIAL_8N1 (like the default in Arduino). Is it correct? Now I needed a port for the TX 9600,8N1 for the Arduino Nano. Timers T1 and T2 in my program are busy generating 8 PWM.
So question 1. Can I use your library to work without a Serial port but using the timer T0? I do not use delays in my program . In Arduino Nano they are generated on timer 0.
Question 2. Can I use your library to work with the Serial port, turning it off (Serial.end () ), then turn on at 9600 speed, transmit on Tx, then turn it off and on again at 100000 (Serial.began (100000, SERIAL_8E2) )? Thus to organize reception of RX SBUSdata and transfer some others data of Serial TX 9600?
Thank!
Gennady

Hy, it uses fine on Mega, on UNO but seems stucked on NANO V3 (ATmega328p), is it not possible ? I have add Softawre serial to be able to readsome debugs which work on UNO but no possibility to see anything on Arduino Nano. On a program I am making for rc model lighting using SBUS from channel 9, I get running on UNO but not on Nano. Nothing happens.
I am trying since a week now and a good advice if NANO yes or no would be nice.
Otherwise it is a perfect library.
Thanks for reply,
André
